Robert Allan JamesandClaude Sonnet 5 d55ec3241b starkernel: item 3.1 -- the Stadium cell and header
Punch list §25 item 3.1 complete.

Defines StadiumPatronHeader and StadiumContinuationCell in new
include/starkernel/vm/stadium.h, unioned as StadiumCell per §3's
closed two-valued union. src/starkernel/vm/stadium.c added to
Makefile.starkernel's LOADER_EXTRA_SRCS/KERNEL_EXTRA_SRCS so the
header's compile-time size checks are actually compiled, not merely
included by something that never builds.

Discriminator ruled an external side bitmap (Captain Bob), not a
header field -- amended into §3 and §23.3 before this code was
written. Item 3.1 declares the bitmap's purpose/indexing in a comment
only; allocating it is item 3.2's scope.

Both cell shapes counted for real at exactly 64 bytes with zero
compiler-inserted padding (three C99-portable negative-array-size
assertions -- no _Static_assert, this project targets C99). Header
matches §23.3's original 32+32 split unchanged, since the
discriminator moving outside the cell left nothing to compete for that
space. Continuation cell matches item 1.12's 4+60 figure unchanged for
the same reason.

Verified the size assertion is actually live: broke it to 63,
confirmed the build failed with the expected negative-array-size
error, restored it, confirmed a clean compile.

Verified: three-architecture boot (amd64, aarch64, riscv64), all
reaching ok> with identical dict_hash=0x3d4e1daf289da94f matching the
item-2.2 baseline. Confirmed stadium.o present in both obj/loader/vm
and obj/kernel/vm post-build on amd64, closing the gap the item-2.2 WIP
exposed (an uncompiled header proves nothing).

Left open, not fabricated: §23.4 #2 ("does a typical message fit in
one cell") is unanswerable today -- no message patron struct exists
anywhere in this tree yet.

Public headers for the hosted StarForth VM (src/). Kernel-only headers live under include/starkernel/.

Core VM

  • vm.h — the VM struct and all core types (DictEntry, DictPhysics, stacks, dictionary state); the central header most other files include.
  • vm_api.h — external VM API surface.
  • vm_host.h, vm_debug.h, startup.h, version.h — host integration, debug utilities, startup sequencing, version string.
  • cli.h, repl.h, io.h, log.h — CLI parsing, REPL loop, I/O, logging.
  • word_registry.h — word registration system shared by every src/word_source/*.c file.
  • compudynamics.h — the generic compudynamics module: tuning-word/config lookups (cd_tuning_word(), cd_tuning_vm()) consumed by ssm_jacquard.c.

Memory / blocks

  • memory_management.h, dictionary_management.h — dictionary allocator and search.
  • block_subsystem.h, blkcfg.h, blkio.h, blkio_factory.h — logical→ physical block mapper and pluggable block I/O backends (file/RAM).
  • platform_alloc.h, platform_lock.h, platform_time.h — platform abstraction shims (hosted vs. kernel allocation/locking/timing).

Physics-driven adaptive runtime (7 feedback loops)

  • physics_runtime.h — main physics coordinator.
  • physics_hotwords_cache.h — Loop #1, execution-heat hot-words cache.
  • physics_metadata.h — per-word DictPhysics metadata tracking.
  • physics_pipelining_metrics.h — Loop #4, word-transition prediction.
  • physics_execution_hooks.h — execution instrumentation hook points.
  • rolling_window_of_truth.h, rolling_window_knobs.h — Loop #2 circular execution-history buffer and its tuning knobs.
  • inference_engine.h — Loops #5/#6, window-width and decay-slope statistical inference.
  • dictionary_heat_optimization.h — Loop #1 heat counters.
  • ssm_jacquard.h — L8 Jacquard steady-state mode selector.
  • doe_metrics.h — Design of Experiments (2^7 factorial) metrics.
  • profiler.h — performance profiling hooks.

Arithmetic / codegen

  • q48_16.h — Q48.16 deterministic fixed-point arithmetic (used instead of IEEE-754 float specifically to keep cross-architecture behavior bit-identical).
  • math_portable.h — portable math helpers.
  • arch_detect.h, starforth_config.h — architecture detection and the build-flag fallback-default layer (used when a .c file is compiled by hand without make).
  • vm_asm_opt.h, vm_asm_opt_arm64.h, vm_asm_opt_riscv64.h, vm_inner_interp_asm.h, vm_inner_interp_arm64.h, vm_inner_interp_riscv64.h — per-architecture assembler-optimized inner interpreter (USE_ASM_OPT=1).
